Answer:
3 + 5i.
Step-by-step explanation:
(2−√−4)+(1+√−49)
√−4 = 2i and
√−49 = 7i.
So (2−√−4 + (1+√−49
= ( 2 - 2i) + (1 + 7i)
= 3 + -2i + 7i
= 3 + 5i.
Answer: ( D) Exponential growth
Step-by-step explanation:
Answer:
X + X + 1 + X + 2 = 72
3X + 3 = 72
3X + 3 - 3 = 72 - 3
3X = 69
3X/3 = 69/3
X = 23
Step-by-step explanation:
To solve for X, you first add the integers together and the X variables together. Then you subtract three from each side, followed by dividing by 3 on each side.
